I don't know, but I looked up one of the dates to see where Obama was on that day ... March 04, 2009.
March 04, 2009 Obama was giving a speech at the Eisenhower Executive Office Building in Washington, D.C.

Wrong. That's a set of entry/exit stamps from the European Union, where the day is listed before the month. So the date shown for entry is April 3, 2009. Obama arrived in France that day for the NATO summit.
